“The attack originated from over 122,145 source IP addresses spanning 5,433 Autonomous Systems (AS) across 161 countries.”
A record 7.3 Tbps attack pushed 37.4 TB at one IP in 45 seconds. Telefonica Brazil and Viettel carried about a fifth of it. Part of the flood bounced off QOTD, Echo and RIPv1, protocols that should have been switched off decades ago. Big ISPs keep forwarding this garbage because nobody makes them stop.
